Fan Fuse keeps blowing..... HELP!
The fan fuse (under the hood) keeps blowing on me and then my car starts to overheat.... It is only this fuse and no other. I know it has to be something in the wiring but i know that if i take it anywhere the guys in the shop will sit around and scratch their heads while they spend my money doing nothing.... I was wondering if anybody could tell me what to look for or what would be causing this.... Throwing codes 77(fan), 83(reverse inhibit), 84(skipt shift)... They are all linked on the same fuse so when i replace the fuse the codes go away.... until the fuse blows AGAIN.... HELP!!!

That fuse powers:
O2 sensors reverse lock out solenoid skip shift solenoid EVAP solenoid EGR solenoid fans The most common thing I have seen that causes the fuse to blow is a burned and grounding out O2 harness wire. I would check that first. People with headers seem to be more vulnerable. :D |

How do i see if its "grounded"? |
if any part of the wire is shorted to a ground, or grounded, it simply means that the wire itself (metallic conductor core, under the insullation) is touching some sort of metal, as in the 02 wires melting through the plastic insullator and the metal wire touching your exhaust pipe. You most likely have some wire shorting to ground somewhere like this. Hope this helps. J-Bird

Does it happen when one of the fans is on? Maybe a fan is bad and pulling too much current.

Originally posted by shoebox Does it happen when one of the fans is on? Maybe a fan is bad and pulling too much current. Is that a possibility? Has that happened before? IF so how do i test it....... Just replace the fans? |
Do you still have the Air pump on the car? I kept blowing the A/P FAN fuse and figured out it was the A/P locked up blowing fuses.
Just an idea. Just unplug both connections on the A/P. It wont cause a code to pop! |
No airpump removed when the headers went on last summer..... Any other ideas???
|
Now its blowing the fuse as soon as i put it in........ I really dont want to take it anywhere because they are just going to sit around and scratch their heads while they charge me out the ass to fix it....

If its the fan fuse, there was a bulliten out on it. The fix is to replace the wire with the next larger gage and move up to a 25 amp. This is common in the problem in the winter month.:bow:
